形成されている。The upper surface 1a of the push button 1 is formed in a curved shape in order to improve the feeling of operation at the time of keystroke, and has fine irregularities to prevent reflection of external light at the time of operation.
Further, characters, symbols, figures, etc. (hereinafter collectively referred to as function display) 2 for displaying the function of a push button switch (not shown) to which the push button 1 is attached are printed on the upper surface 1a. Further, a protective film 3 made of transparent or semi-transparent matte hard ink is formed on the functional display 2 in the area covering the functional display 2 (the portion surrounded by the broken line indicated by arrows A 1 and A 2 in the figure). ing.
上記機能表示２の印刷及び保護膜３の形成は押釦１の上
面部1aにいわゆるパッド印刷（直接インクを印刷する印
刷手段の一つ）を用いて行う。ここでパッド印刷につい
て以下簡単に説明しておく。パッド印刷とはグラビア・
オフセット印刷の一種で、柔らかいシリコンラバーパッ
ドを用いて印刷を行うため、パッドが被印刷物の表面形
状に沿って自在に変形し、従来の印刷方式では不可能と
されていた凹凸面や三次元曲面への印刷が行えるという
特徴を有する。The printing of the function display 2 and the formation of the protective film 3 are performed by using so-called pad printing (one of printing means for directly printing ink) on the upper surface 1a of the push button 1. The pad printing will be briefly described below. What is pad printing?
As a type of offset printing, printing is performed using a soft silicone rubber pad, so the pad can be freely deformed along the surface shape of the printed material, resulting in uneven surfaces and three-dimensional curved surfaces that were impossible with conventional printing methods. The feature is that it can be printed on.
具体的な印刷手順としては、まず第３図に示す如く所定
の機能表示に対応する凹部４を形成してなる凹版５にス
パチュラー６にてインク皿７よりインク８（図中、梨地
で示す）を流し込み、続いて第４図に示すように余分な
インク８をドクターブレード９で取り除き、上記凹部４
のみにインク８残す。As a specific printing procedure, first, as shown in FIG. 3, an intaglio 5 formed by forming a recess 4 corresponding to a predetermined function display is ink 8 from the ink tray 7 by the spatula 6 (shown as satin in the drawing). Then, excess ink 8 is removed by a doctor blade 9 as shown in FIG.
Leave ink 8 only.
次に第５図に示すようにこの凹版５にシリコンラバーよ
りなるパッド10を挿入して凹部４内にあったインク８を
パッド10に転移させ、このインク８が転移されたパッド
10を第６図に示すように被印刷物（本実施例では押釦１
の上面部1a）に押圧することにより印刷が行われる。Next, as shown in FIG. 5, a pad 10 made of silicon rubber is inserted into the intaglio plate 5 to transfer the ink 8 in the recess 4 to the pad 10, and the pad to which the ink 8 has been transferred
As shown in FIG. 6, 10 is an object to be printed (pushbutton 1 in this embodiment).
Printing is performed by pressing on the upper surface 1a) of the.
このパッド印刷によれば、金型を用いる二色成型による
文字等の形成と比べて金型が不要なためコストの低減を
図ることができ、また細い線の使用が可能となる他、印
刷された文字等の明確度，鮮明度が向上し、更には多色
印刷をも行うことができる。According to this pad printing, it is possible to reduce the cost because a mold is not required as compared with the case of forming characters etc. by two-color molding using a mold, and it is possible to use a thin line and to print. The clarity and definition of letters and other characters are improved, and multicolor printing can be performed.
再び第１図に戻って説明すると、機能表示２及び保護膜
３は上記パッド印刷を用いて形成されている。即ち、先
ず押釦１の上面部1aに通常のインクを用いて所定機能表

る。ここで第１図におけるＢ−Ｂ線に沿う押釦１の断面
を第２図に示す。尚、説明の便宜上、機能表示２及び保
護膜３の厚さ寸法は誇張して描いている。Referring back to FIG. 1 again, the function display 2 and the protective film 3 are formed by the pad printing. That is, first, the predetermined function display 2 is pad-printed on the upper surface 1a of the push button 1 using normal ink, and then the protective film 3 made of hard ink is pad-printed only on the portion substantially covering the function display. Here, FIG. 2 shows a cross section of the push button 1 taken along the line BB in FIG. For convenience of explanation, the thickness dimensions of the function display 2 and the protective film 3 are exaggerated.
同図に示すように通常インクよりなる機能表示２は硬質
インクよりなる保護膜３に被覆された状態となってい
る。即ち、機能表示２は直接外部に露出されておらず、
直接外部に露出しているのは硬質インクよりなる耐摩耗
性に優れた保護膜３である。よって、機能表示２は通常
インクを用いたパッド印刷により低コストでかつ鮮明に
形成することができ、また保護膜３の存在により耐久性
を向上させることができる。As shown in the figure, the function display 2 made of normal ink is in a state of being covered with the protective film 3 made of hard ink. That is, the function display 2 is not directly exposed to the outside,
Directly exposed to the outside is the protective film 3 made of hard ink and excellent in abrasion resistance. Therefore, the functional display 2 can be clearly formed at low cost by pad printing using normal ink, and the durability can be improved by the presence of the protective film 3.
ここで注目すべきことは、保護膜３の形成部分は機能表
示を実質上覆う部分のみであることである。通常、押釦
１の表面全体にわたり文字，記号等を記載することはな
く、よって押釦１の上面部1aは、外光と反射を防止する
微細な凹凸が形成された部位と、保護膜３が形成された
部位とにより構成されることになる。What should be noted here is that the portion where the protective film 3 is formed is only the portion that substantially covers the functional display. Normally, characters, symbols, etc. are not described on the entire surface of the push button 1. Therefore, the upper surface 1a of the push button 1 is provided with a portion where fine irregularities are formed to prevent reflection of external light and a protective film 3 is formed. It will be constituted by the part.
保護膜３の形成は、パッド印刷を用いることにより比較
的容易に行うことができる。また機能表示２の印刷時に
用いる凹版５と同一の凹部を形成してなる凹版を用いる
ことにより、第７図に示す如く、機能表示２と完全に重
畳する保護膜３を形成することも可能である。The protective film 3 can be formed relatively easily by using pad printing. Further, by using an intaglio formed by forming the same recess as the intaglio 5 used when printing the function display 2, it is possible to form the protective film 3 which completely overlaps the function display 2 as shown in FIG. is there.
前記したように、押釦１の上面1aには操作性を向上させ
るため、外光の反射を防止する微細な凹凸が形成されて
いる。今、この上面部1a全体にわたり保護膜３を形成し
た場合を考えると、機能表示の保護という機能は奏する
ものの、外光の反射を防止する微細な凹凸は塞がれてし
まい反射防止機能を奏さなくなる。従って、保護膜３の
形成後に反射防止の為の加工を実施せねばならず、製造
工程が徒に複雑になり製品コストも上昇してしまう。As described above, the upper surface 1a of the push button 1 is formed with fine irregularities for preventing the reflection of external light in order to improve the operability. Now, considering the case where the protective film 3 is formed over the entire upper surface portion 1a, although the function of protecting the functional display is achieved, the fine irregularities that prevent reflection of external light are blocked and the antireflection function is achieved. Disappear. Therefore, after the protective film 3 is formed, processing for preventing reflection must be performed, which makes the manufacturing process unduly complicated and increases the product cost.
上記上面部1a全体にわたり保護膜30形成する手段として

る。これに加えてスプレー塗布のばあい、インクの使用
効率が悪く、殆どが大気中に拡散されてしまう為（使用
効率は10〜20パーセント程度と思われる）、コスト高と
なってしまう。As a means for forming the protective film 30 over the entire upper surface portion 1a, spray coating can be considered. However, in the case of forming the protective film by spray coating, the following problem occurs in addition to the above problem of antireflection. That is, when applying coating to a single push button, it is necessary to fix the push button using a double-sided tape or the like on the jig (because it is blown off by the pressure of the spray), the coating work is troublesome, and the keyboard switch When the coating is carried out after the assembly, the masking process must be carried out so that the hard ink does not adhere to the portion other than the coating portion of the push button, and the coating work is also troublesome. In addition to this, in the case of spray coating, the use efficiency of the ink is poor, and most of it is diffused into the atmosphere (use efficiency seems to be about 10 to 20%), resulting in high cost.
しかるに機能表示２を実質上覆う部分にのみ保護膜３を
形成する本考案の構成では、機能表示２を確実に保護し
耐久性を向上させると共に反射防止を行う凹凸の全部が

る。However, in the configuration of the present invention in which the protective film 3 is formed only on the portion that substantially covers the functional display 2, the functional film 2 is reliably protected and the durability is improved, and all the irregularities that prevent reflection are covered by the protective film 3. There is no such thing as peeling. Further, since the protective film 3 is a matte hard ink and has a limited formation range, the reflection by external light does not pose a problem in operation. In addition to this, it is possible to easily print the function display and the protective film 3 after being incorporated in the keyboard switch, and the use efficiency of the ink is high, and the product cost of the push button can be greatly reduced. .
